If you hair color treated hair do not use the shampoo...it will strip the color out of your hair- espically if you have red tones (which are very delicate). I have no problem bringing my own hair care products espically after spending $400 on hair color.
The only thing its good for IMHO is to wash out your bathingsuits.
We also got toothbrushes but we did stay concierge so I'm not sure about regular rooms. We did have our own but I guess she was leaving them for my DD12. They are just a generic red toothbrush but are package like the soaps are.
Be on the safe side and bring your own toiletries. I am sure that DW buys in massive bulk, and educated guess here it's NOT Biloage, Paul Mitchell or some other salon quality product.
